BICYCLE Fil 17 1921 2 Shets-heet 1 tially semicylindrioal and disposedat an obtuse angle to the lower portion of theplate 20. Another plate 23similar to the plate is provided, this also being formed with an opening24 having an axle engag ing portion similar 'to the portion 22., Theplate 23 is disposed oppositely to the plate 20 so that the bearingportion 25 overhangs the bearing portion 22. The two Plates are adaptedto be plaoed on opposite faces of the arm of the fork so that theportion 25 Will extend through the upper part of the opening 21 in plrte20 whilethe bearing portion 22 will extend into the lower portion oftheopening, 24'in plate 23. A slot 26 is provided inthe man 50 as toreceive these bearing portions 22 and 25 as shown in Figure 16. It is tobe understood that the plates may be astenedto the arm of the fork byineans ot rivets 27 Ont-ho like extending therethrOugh as shown" inFigure 16. J

The bearii1gs desoribed adapted to re- 1 ceive the end portions of axles28. Eaoh of these aXles is provided with lo1igitudinal fins for keys 29and eaoh aXle is adapted to be .inserted lngitudinally into a metalbarrel *or sleee 30 having longitudinally extnding o utstanding portions31 for the reception of the keys or fins 29.. This barrel or sleeveconstitutes the hub of one of the wheels of the veliicle. On each end ofthe barrel 30 pis mounted a pair of oppositely disposed' disks 32 and 33having openings 34 at the Centers thereof so.shaped as to fit snuglyupon the ends of the barrel. Eaoh opening is proferabl provided withalaterally ex tending .fiange 34 'andWhen the disks of one pair areasSembled the flanges 34 thereon areextended toward eoh other and meetas'shown particularly in Figure 7. One

' disk,33, of each pair has ears 35 at the periphery thereof and theseears are adapted to be bent laterally toward the disk 32 so as toprovide means for engagement with the inner end portions flof spokes 36the other nd portions of whioh are Connected to the rime 3701? thewheels. r

The 'aXle of the frontwheel is extended laterally beyond the bearings inthe front fork and mountedon eaoh end of this'front axle is the eyeportion of a pedal orank 38 fastened to the aXle in any suitable manner.Obvi0usly a .Vehiole such as herein des'cribed can be made oheapl andwill constitute a satisfactory velooipede for small ohildren.

It is to be understood of course that various changes may be made in theconstruotion of the bearing shown in Figures 16, 17 and 18 and in theconstruction of the wheels as well as other details .of the in-Vent-ion.

As shown n Figures 19 and 20 the bear- 1ngs can be made somewhatd1fferently from the one illustrated in'Figures 16, 17 and 18.

This 1nodified form of bearing includes an inneir plate 44 adapted tofit snugly against the inner side of ar1n 41 of the fork and hav- 1ng anoutwardly extend1ng, arouate bear1ng prmect1on 45 eXtend1ngtr:insversely under the lower end of the forked ami 41, said preferablyextended through a slot 47 in the inner plate 44 so that by looseningthe 'lower bolt said inner plate can be adjusted upon' theupper boit 46to reduoe the distance between the bearing members 42 and 45 and thustake up wear. 7 If desired that face of the plate 44 engaging the arm 41oan be serrated or'roughened so as to properly en 1 gage thearnrwithoutslipping as shown in Fig. 19

' What is Claimed is:

In a bicycle, a fork inoluding conneeted strips having out away portionsforming the arms of the fork, a frame inoluding horizontal bars, andhinges eaohhaving a leaf extending between and clamped loythe strips ofthe' front fork, a leaf extending into and seoured to one of thehorizontal bars, and a handle barstrgddling and seoured to thestrips ofthe front forlz' to hld them 'aga1nst separat1on from the hinge leavestherebetween. i 7

In testimony that we clai1 n the foregoing as our own,'we have lieretoaffixed our signatures in the presenoe of two Witnesses.
